NEW YORK (AP) -- The New York City Council is cracking down on graffiti that uses etching acid to mark on glass.
The council passed a bill Wednesday that requires anyone buying etching acid to show ID, names and addresses.
The store will keep records for one year. The council says the city will use the information to enforce a law banning minors under 21 from buying etching acid.
Etching acid is often used in graffiti on subway windows, bus shelters and store windows. It cannot be removed and the glass must be replaced.
